10/112 Doc ID 018780 Rev 4
STM8L Ultralow power microcontrollers can operate either from 1.8 to 3.6 V (down to 1.65 V
at power-down) or from 1.65 to 3.6 V. They are available in the -40 to +85 °C and -40 to
+125 °C temperature ranges.
These features make the STM8L Ultralow power microcontroller families suitable for a wide
range of applications:
● Medical and handheld equipment
● Application control and user interface
● PC peripherals, gaming, GPS and sport equipment
● Alarm systems, wired and wireless sensors
● Metering
The devices are offered in five different packages from 20 to 48 pins. Different sets of
peripherals are included depending on the device. Refer to Section 3 for an overview of the
complete range of peripherals proposed in this family.
All STM8L Ultralow power products are based on the same architecture with the same
memory mapping and a coherent pinout.
Figure 1 shows the block diagram of the STM8L Low density family.
